Composite panel for reinforcing concrete body

Abstract

Disclosed are a panel for repairing and reinforcing a concrete body, a multi-purpose anchor, an anchor for level adjustment and injection a method for repairing and reinforcing the concrete body using the same, which can connect adhesives and anchors at weak parts of the concrete body, which is neutralized, aged, deteriorated, cracked due to water leakage, or segregated, or at parts requiring the repair and reinforcement due to a change in use environment. The composite reinforced panel includes lightweight concrete, high strength concrete or a steel plate and reinforcing means, thereby being effectively prevented from bad environments causing a drop of reinforcing capacity, providing good heatproof and fireproof properties, and maximizing merits of materials used as the reinforcing means. The multi-purpose anchor has a bolt and an injection pipe, fixes the panel to the concrete body effectively, serves as a spacer maintaining a prescribed interval between the panel and the concrete body, and serves to inject filler and discharge the inside air to the outside, thereby improving construction efficiency. The anchor for level adjustment and injection has a male screw and a female screw at an end and an injection pipe of a straw type, thereby improving the construction efficiency when the concrete panel is installed.

Description

technical field [0001] The present invention relates to a plate for repairing and strengthening of concrete bodies, a multifunctional anchor, an anchor for height adjustment and injection and a method of using these for repairing and strengthening of concrete bodies. More specifically, the present invention relates to a panel for repairing and strengthening a concrete body, a multipurpose anchor, an anchor for height adjustment and injection and a method of using these for repairing and strengthening a concrete body, wherein said panel Ability to attach adhesives and anchors to said weak parts of the concrete body, said weak parts being neutral, aged, damaged, cracked due to water leakage, or detached Parts, or connected parts that need to be repaired and strengthened due to changes in the use environment. Background technique [0002] It is generally considered that the reinforced concrete body is semi-permanent, but the reinforced concrete body is aged and damaged due to ...

AI Technical Summary

Problems solved by technology

However, the reinforcement method using fiber sheets has several problems: Its heat resistance and fire resistance are weak, so when it catches fire, it generates toxic gas and the reinforcement effect drops sharply, resulting in loss of life and property

However, the disadvantage of this method is that due to the heavy weight of the steel plate, (generally 4.5mm and thicker steel plates are used to ensure the required strength) it is difficult to transport and handle materials and safety supervision, and due to welding or other operations In the use of fire, there is a danger

However, although the materials used are good, since the restoration work of the section of the removed concrete body is done by plastering work, the conventional method suffers from the bond strength between the existing concrete body and the restored surface in the section. limited
